No, not yet. Data from HANDLOADER #123, Sep - Oct 1986: 200 gr Norma, 35 gr IMR 3031 = 1800+ fps 200 gr Norma, 38 gr H4895 = 1800+ fps Suggestion: use 38-55 data Obviously use caution when loading for older rifles of unknown action and barrel strength. Cartridges of the World shows factory load of 190 gr. bullet at 1600 - 1700 fps.
thanks for info. this cartridge has a lot of variations in bore/land dimentions. also being a low pressure cartridge in a firearm with stock wood over 100 year age , I want to stay within or actually below original specs.
